In mechanics and engineering applications, the study of rigid body stability holds significant importance. The method of static moment equilibrium is a critical tool for analyzing the stability of rigid bodies. In this paper, a simple and practical non-tipping tube device is constructed, which can maintain balance in quiescent water even under horizontal external force. The functional relationship between the inclination angle of the tube and the external force was obtained through theoretical analysis, and the experimental data modified the theoretical model. The device can detect external force up to 4.11±0.04 N (P=0.95). This intuitive experimental device has potential applications in physics teaching and the fields of wind detection engineering.
